Naw, it's been there since 10.0.0. Without a shortcut: use the text field in the "Help" menu.

It’s quite an old feature. Check whether you have disabled or changed the shortcut under System Preferences > Keyboard > Shortcuts > App Shortcuts > All Applications > Show Help Menu.

The default shortcut might also differ between keyboard layouts.

As the sibling comment said you can also use the text box in the Help menu by clicking it.
